I'm watching both the Korean and Japanese versions because I'm curious whether they only have the same plot and dialogue. Sadly, the Japanese version almost copies everything from the original. They only made changes to the food, sequence of scenes, and some changes to the characters' personalities.

But what made me like the Japanese version more is the improvement they did to some events and dialogues. I fell for Aoi because even though she's rude, her words are not very offensive. I also felt her feelings toward the ML more. She's more lively than her Korean counterpart so I found it funnier every time she tries to flirt with Arata and compete with Yuka. And lastly, she's so cute. I'm having a hard time which between Aoi and Yuka I should ship to Arata.

Korea surely has better cinematography and edits. Also better with some characters' acting. But I don't aim for perfection. As long as it is not disturbing and not ruining the drama, I'm fine with that.
